Even though we live in a very rural area, our local university is doing some research that may help with my husband’s spine surgery. He has a very complex problem. The engineers have developed some kind of model that takes his CT scans and turns them into a 3-D model of his spine. Will the average person ever be able to benefit from something like this?

What you are referring to is called rapid prototyping (RP) technology. Federal money was used to develop and expand the use of RP models in surgery.

Besides complex pelvic and spine problems, this type of 3-D model has been used in bladder surgery, facial surgery, and neurosurgery. The models give the surgeon a better understanding of the changes in anatomy caused by the condition. The models make it possible to create special implants if needed.

Right now RP is only in use in academic (university) settings. In time, as the technology advances, it’s likely that commercial providers will step in and manufacture these. Safety and benefits must be proven first.

It is likely that equipment will be developed specifically for RP modeling for all kinds of surgeries. With increased availability, the cost will come down. Insurance companies may even include such steps as a necessary part of the procedure.

This will depend on studies showing that the model will reduce complications. Fewer errors and shorter operating times will result in decreased problems. Improved long-term results following surgery will also aid in supporting the commercial use of RP models.
